Why does the FCS‑client abort during provision‑data retrieval when the number of owner‑root‑hash slots is changed to 5? - Why does the FCS‑client abort during provision‑data retrieval when the number of owner‑root‑hash slots is changed to 5? Description After provisioning 5 owner root hash, FCS client aborts during get provision data command command for fcs-client on get provision data (read efuse) : ./fcs_client –G <name>.bin -p --loglevel=4 Error message displayed when perform command fcs-client on get provision data on 5 owner root hash: root@agilex:~# fcs_client -G a.bin -p --loglevel=4 [dbg:]Retrieving provision data [dbg:]sysfs attribute /sys/kernel/fcs_sysfs/prov_data munmap_chunk(): invalid pointer Aborted perform owner root hash cancellation for root2,root3, and root4, get provision data command from FCS-client still remain “0”. command for fcs-client cancel owner root : ./fcs_client –c <name>.ccert –c <volatile = 1 / non-volatile =0> Error message displayed when perform command fcs-client on get provision data on 5 owner root after perform owner root hash cancellation for root2,root3 and root4: root@agilex :~# fcs_client -C signed_root4_cancel.ccert -c 1 root@agilex :~# fcs_client -C signed_root3_cancel.ccert -c 1 root@agilex :~# fcs_client -C signed_root2_cancel.ccert -c 1 root@agilex :~# fcs_client -G a.bin -p W0:Provision Status Code: 0x0 W1:Key Cancellation Status: 0x7F W2:Co-Sign Status: 0 W2:RootHash0 Cancel Status: 0 W2:RootHash1 Cancel Status: 0 W2:RootHash2 Cancel Status: 4 W2:RootHash3 Cancel Status: 0 W2:RootHash4 Cancel Status: 0 W2:Number of Hashes: 5 W2:Type of Hash: secp384r1 Resolution To avoid this problem, upgrade the libfcs with install the following patch: fix_read_provision_5_root_hash_v2.patch This problem is scheduled to be resolved in a future release of the libfcs.
